Characterizational Measurements of a Model Wind Turbine in a Variable Density Wind Tunnel — •Birte Thiede1, Christian Küchler1, Julian Jüchter2, Michael Hölling2, Eberhard Bodenschatz1, Joachim Peinke2, and Michael Wilczek1 — 1Max Planck Institute for Dynamics and Self-Organization, Göttingen — 2ForWind, Institute of Physics, University of Oldenburg, Oldenburg
Wind tunnel experiments with small-scale models are an essential part of wind turbine research as they offer a highly controllable environment for the investigation of various research questions. Due to the limited size of wind tunnels, the Reynolds numbers that can typically be achieved in such experiments are significantly smaller than those in actual wind turbine systems.
The Variable Density Turbulence Tunnel at the Max Planck Institute for Dynamics and Self-Organization can be filled with the dense gas SF6 and pressurized up to 15 bar, which leads to sufficiently high Reynolds numbers ( up to 2 · 107) to perform wind turbine experiments at dynamic similarity.
In this tunnel, we study the power generation as well as the wake characteristics for different turbulent inflow conditions (generated by an active grid) and a range of Reynolds numbers of the MoWiTO 0.6, a model wind turbine built at the ForWind Center for Wind Energy Research Oldenburg, which is equipped with a pitch- and a load control.
